Answer:
Ionic or Electrovalent Bonding
Explanation:
There are primarily two categories of bonding between chemical entities. We have; Ionic Bonding and Covalent Bonding.
Ionic bonding or electrovalent bonding is the complete transfer of valence electron(s) between atoms. There is the transfer of electron from typically a metal to a non metal.
Covalent Bonding however involves the sharing of electrons between atoms. Depending on whuch atoms provide the electrons, it can be ordinary covalent oor coordinate covelent bond.
Answer:
2-methylene propylbenzene
Explanation:
The Wittig Reaction is a reaction that converts aldehydes and ketones into alkenes through reaction with a phosphorus ylide.
The ketone in this case is 1-phenylpropan-1-one. The provided phosphonium ylide is shown in the image attached. The reaction involves;
i) alkylation
ii) addition
The product of the major organic product of the reaction is 2-methylene propylbenzene.
<span>Water soaks into it easily and during freeze-thaw cycles would be more likely to break apart because of the water freezing and thawing inside the rock. The water freezes and expands inside the rock, causing the surface to break off in flakes from the pressure of the expanding ice inside.</span>
